The God of Death

The growth of life on Earth was enough to attract the first impact of an array fragment, this one being aligned with the cold/ice element. This led to the first extinction event on Earth, and the natural evolution of this fragment to become a Geocarpic Omniscient Particle, something later known as the God of Death.
The God of Death was neutral at first, but after the emergence of Highmortals on Earth and with them self inflection and the concept of murder, it continued to evolve to become more skewed towards evil. The influence of the God of Death was not the source of death, but assumed it's governance which then inherently made it a permanent fixture in the pantheon of Earth.
Death itself is a natural law of morality and not controlled directly by the God of Death, but instead a tool used by the Geocarpic Omniscient Particle to cause more death. This is done through two primary means. New sicknesses, infections, and other health related ailments are the first, and instilling the hunger to kill in Highmortals is the second.
Not all ailments are necessarily created by the God of Death, but most can be traced back to roots that have been confirmed to have traces of the Gods influence.
Things like serial killers, as well as the people the break down in a fit of violence, or people that see the world as something that needs to be proven wrong through a massacre...these are all things that are either directly created by, or at the very least enhanced by the God of Death.

The first god to arrive on Earth 440 million years ago, and the true cause of the Ordovician-silurian Extinction.

"The God of Death may be a scary moniker, as it should be, but understand that the fragment was neutral when it arrived. It was the implication of mankind that led to the corruption of the God."

Practitioners of divine arts that follow the God of Death tend to work from one of two angles, the first to try and understand the God of Death through understanding and curing the ailments it has created, seeing these as challenges that were given to Highmortals to overcome and ultimately become stronger for. The second is to work as an agent of the God of Death, as the influence of any God is limited to only that, influence. Things created by the God that are inherently evil, like serial killers for example, are not created by the god because it is evil, this being because Highmortals were the source of that evil to begin with. They see this as a punishment for history and its endless war and death, and seek to be the beacons working to stop the perpetuation of the cycle of death. They work to actively stop those that commit murder both on the individual and macro scale.
